4. The agitating type pebble coal classifier of claim 3, wherein the second driving mechanism comprises a bucket elevator motor (410), a bucket elevator speed reducer (420), a transmission chain wheel and a transmission chain which are sequentially connected, and the transmission chain is wound around the transmission chain wheel and the bucket elevator chain wheel at the same time.
5. The agitating type pebble coal classifier of claim 2, further comprising a two-stage bucket elevator (600) provided to the frame (100);
the two-section bucket lifting device (600) comprises a third driving mechanism, two-section bucket lifting chain wheels, two-section bucket lifting chains (640) and a plurality of gangue hoppers (650) fixedly arranged on the two-section bucket lifting chains (640), wherein the third driving mechanism can drive the two-section bucket lifting chain wheels to rotate so that the two-section bucket lifting chains (640) drive the plurality of gangue hoppers (650) to sequentially pass through the lower part of the fourth discharge outlet;
the two-section bucket lifting chain (640) is obliquely arranged, and when the coal gangue hopper (650) moves to the upper limit position, the coal gangue hopper (650) pours out the coal gangue in the two-section bucket lifting chain.
6. The agitating type pebble coal sorting machine of claim 5, wherein the third driving mechanism comprises a two-section bucket elevator motor (610), a two-section bucket elevator speed reducer (620), a two-section transmission chain wheel and a two-section bucket elevator transmission chain (630) which are sequentially connected, wherein the two-section bucket elevator transmission chain (630) is wound on the two-section transmission chain wheel and the two-section bucket elevator chain wheel at the same time.
7. A sorting apparatus comprising a dewatering device for dewatering coal discharged from the agitating stone coal sorter as described in any one of claims 1 to 6, and the agitating stone coal sorter.
